Hello all. I've been quietly watching this thread like a hawk and reading it like my life depends on it. Sorry if I haven't post anything.

this will be our groups second attempt (first one last Oct and the strong wind stopped us reaching the Mirror Lake). Our schedule is like this:
7/14/17: Arrive at Whitney Portal Parking Lot to sleep after checking Alabama Hills.

7/15/17: From Whitney Portal to Trail Camp (will spend most of our time at that elevation to get acclimated and check out the rest of the area)

7/16/17: Actual Summit day (leaving the camp around 4 am) and will head back down to our car after.

We are prepared with crampons, ice ax and helmet and other backpacking gear (thanks to all your tip, it help us minimize the weight and be prepared mentally)

now my major concern is, I'm afraid the history will repeat itself again...the weather this Sat and actual summit day turns sour, rain showers and risk thunder storm :-(

Our group is now consist of two people. What should I do?
